(Granted under the act of March 3, 1883, as amended A131130, 1928; 370 0. G. 757) 4 Claims.

'Ihis application is made under the act A of March 3, 1883, as amended by the act of April 30, 1928, and the invention herein described, if

patented, maybe manufactured and used by or for the Government of the United States of f America for governmental purposes without the payment to me of any royalty thereon.

I hereby dedicate the invention herein described to the free use of the people in the territory of the United States to take keiect on thel granting of a patent to me.

This invention relates to building structures, with particular reference to prefabricated building panels,4 and has among its objects the provision of a panel structure which can be nailed to the framing of a building without nailing through the face of the panel, and which has a tongue and groove tting, such as shiplap, center tongue and groove, or any other conventional tongue and groove type, at the edges of the panel .structure without formation of the tongueand groove on the edge of the panel itself; the provision of a panel structure for use with a drip cap, wherein the drip cap, when installed,`covers the nails which secure the panel structureV to the framing; and such other objects as will be apparent from the following. description and claims.

Referring to the accompanying drawings:

Figure 1 is a three-dimensional fragmentary viewshowing a building framing-With a number of panel structures secured thereto;

Figure 2 is a three-dimensional view with a backside of the panel structure showing;

Figure 3 is/'a partial section on line 3-3 of Figure 1; y

Figure 4 is a partial section on line 4-4 of y Figure 1;

Figure 8 is a section substantially corresponding to Figure 7 without the drip cap in place.

nails. The panel itself is of conventional form, such as plywood or individual pieces of board i secured edge to edge on the cleats.

As illustrated in the drawings with reference to Figures 1 through 4, the panel II is provided at its four edges and on its backside with cleats l2, '|3, I4, and l5 of similar thickness secured thereto. A pair of adjacent cleats, such as I2 and I 3, is offset outwardly from the edges of the panel a fractional distance of the width of the cleats, and the other pair of adjacent cleats, such as I4 and I5, is offset inwardly the same distance. One pair is provided with tongues I6 and and the other pair with mating grooves I8 and I9.

The panel is secured to a building framing, such as studdings 20, by nails or other fastenings passing through the exposed portions of the outwardly loffset'. cleats, as shown at 2|. 'I'he adjacent panel, when secured in place, covers the nails due to the inward offset of its cleats, and is held along the edges provided with the inwardly offset cleats by the tongue and groove fitting. Thus, a Wall of any desired dimensions can be built from these panels without exposure of the nails.

With reference to the embodiment illustrated in Figures 5 through 8, which is particularly useful for outside walls, the panel is shown as In general, according to the invention, a rec'- tangular-shaped panel is provided with cleats secured on its backside at the edges so arranged that portions of the cleats are exposed for nailing and the cleats are provided at their outer edges with a tongue and groove tting, the structure being such that when several panels are fastened to the frame of a building, the panels,

or drip caps in case they are used, cover the formed from a plurali'ty of pieces laid edge to edge with cleats 3| and 32 of similar thickness secured thereto at opposite edges. Both cleats are offset outwardly from the edges of the panel, onev being provided with a groove 33 and the other with a mating tongue 34. These panels are secured to a framing 35 with tongues and grooves of adjacent cleats mated and with fastenings -passed through the exposed portions of the cleats,

as shown at 36. Opposite edges of the panels are beveled in the same direction, as shown at 31 and 38. `This provides a groove 39 between adjacent panels having parallel walls inclined downwardly.

The total outward offset of mating cleats is such that the groove is of proper size to lit a. drip cap 40 inserted th'ereln and secured with fastenings as shown at 4|. Thus, the drip cap covers the fastenings used for mounting the panels. l

Having thus described the invention, what is claimed is:

1. A panel structure comprising: a rectangular-shaped panel, a pair of cleats of similar thickness secured thereto at adjacent edges of the wardly from the edges of the panel a fractional distance of the width of the cleats, a second pair of cleats of similar thickness secured at the remaining adjacent edges of the panel on the backside thereof and oilset inwardly the same distance, one pair of cleats being provided with tongues on the outer edges and the other pair with mating grooves.

2. In a. building having a framing, panel structures secured to lthe frame to form a wall, each panel structure comprising a rectangular-shaped panel with cleats of similar thickness secured thereto at opposite edges of :the panel on the backside thereof and oil'set outwardly from the edges of th'e'panel, tastenings passing through' the exposed portions of the cleats and into the framing, the panel structures being arranged edge to edge with the cleats abutting, thus formins a groove between adjacent edges of the panels, and a drip cap secured in the groove and covering the fasteninss.

.3. In a. building having a framing, panel structures secured to the framing to. form a. wall, each panel structure comprising a rectangular-shaped panel with cleats of similar thickness secured to opposite edges lof the panel on the back side thereof, at least one of the cleats being ollset outwardly `from the edge of the panel a. fractional cleats abutting mated.-

. o! cleats being distance of the width of the cleat, one cleat being provided with a tongue on its edge and the other with a mating groove, fastenings passing through' the exposed pvrtion of the outwardly offset cleat and into the framing.- the panel structures being arranged edge to edge with the and the tongues yand grooves 4. In a building having a framing, panel structures secured to the framing to form a wall, each panel structure comprising a rectangularshaped panel with a pair of cleats of similar thickness secured to adjacent edges of the panel on @the back side. thereof and oiset outwardly from the edges of the panel a fractional distance of the width of the cleats and a second pair of cleats of. similar thickness secured to the remaining adjacent edges of the panel on the back side thereof and oii'set inwardly the same distance, one pair /provided with tongues on their outer edges and the other pair with mating grooves, fastenings passing through the exposed l portionsoi the outwardly offset cleats and into the framing, the panel structures being arranged edge to edge with the pairs of cleats abutting and with 'the tongues and grooves mated.
